Abstract

L'invention concerne des systèmes et des procédés pour une conversion de signal avec une multiprise intelligente. Des modes de réalisation des systèmes peuvent être extensibles sur des topologies de signaux différentes selon le modèle, des fréquences de transmission, des bandes passantes, et des distances. Un mode de réalisation exemplaire des systèmes et des procédés comprend une fibre optique vers un convertisseur RF et une multiprise intelligente. Bien qu'une fibre optique vers un convertisseur RF soit utilisée dans des modes de réalisation exemplaires dans la description, une conversion entre d'autres topologies de signaux est comprise dans la portée de la description. La multiprise intelligente comprend une prise multiple pour distribuer un signal à des terminaux multiples et un microprocesseur pour sélectionner un terminal particulier pour un signal. Des modes de réalisation exemplaires comprennent des mises en œuvre dans le sens descendant dans lesquelles un flux est envoyé généralement depuis un serveur de prestataire de services à un utilisateur. Des modes de réalisation alternatifs comprennent des mises en œuvre dans le sens descendant ainsi que des mises en œuvre dans le sens montant dans lesquelles un utilisateur envoie généralement un flux vers un serveur de prestataire de services.
